I found a blog post from a couple who saw teams from the Amazing Race while in line at customs at Heathrow.

After exiting the plane and waiting for hubby to relieve himself, I was faced with Bear Grills - you know the bloke from Man V's Wild. I find him totally fake and annoying, yet I wanted to get my camera and get a snap. Sadly he was off in his cargos and dark sunnies and big hat before I could reach and grab it from my backpack.

The mornings excitement did not stop there. As we were making our way along what seemed to be a 20km walk to the customs area there were two chicks with huge back-packs, and matching outfits charging past us all, pushing and shoving. Michael whispered to me "amazing race"!!! "Yeah as if" I quipped. Then 2 mins later the camera, and sound crew came charging through, trying to catch up. 10 mins later all the teams were charging through us trying to be the first team to get to the gates.

It was so very exciting, a buzz filled the customs area - which as you all know is a nice change as normally it's a long boring wait to get that stamp and the all clear to collect your bags. For any Amazing Race fans, you will be pleased to know I called over the black team, a guy and gal with a few tats and a nice demeanor and offered them the spot in front of us in line - which they accepted gracefully. Sadly no-one else would let them pass. What tossers, hello they are racing for a million bucks!!!!

I posted a couple of questions (what color outfits were the women wearing, how many other teams were there besides the women and the black team) and I'll wait to see if they are able to reply.

Gah, Sam, ya beat me to it! I'm going to google maps and see how long it says the trip should take, might give us a rough idea of validity, since Joey has no location listed on his twitter page.

ETA: Google maps says 18 minutes, and there was 16 minutes between tweets, so it is possible.

I'm not too sure about it. If I read back right, the flights arrived around 7am here which was 10 and a half hours ago, so either the teams he is with are really slow or there has been a small break somewhere.
